This invention relates to bearings and more particularly to bearings ofthe thrust type.

It is an object of the invention to provide a bearing of the thrust typefor application to the shaft of a variable condenser.

It is a further object of the invention to provide a bearing havingadjustable means for varying the frictional retarding force opposingrotation of the shaft.

y A still further object of the invention is to produce a bearing ofsimple construction which is cheap to manufacture and easy t0 assemble.

YWith these general objects, and others not specifically mentioned, inView, the invention resides in the combinations, features, details ofconstruction, and arrangements of parts which will first be described inconnection more particularly pointed out.

In the drawings:

Figure 1 is a plan view of a construction embodying the presentinvention;

Figure 2 is an end elevation thereof;

Figure 3 is a cross-sectional view taken as on the line 3 3 of Figure 2;

Figure 4 is a cross-sectional view taken as on the line 4 4 of'Figure 1.

Referring to the drawings, there is shown a portion of a shaft 10 whichmay, for ex- Y ample, be the shaft for the rotor of a variablecondenser. As shown, the shaft extends through and is journalled in theframe 11 of the condenser. To this end, the frame plate 1l is swelled asat 12 to provide the metal for the bearing. The plate 11 is alsoequipped with an integral rib or collar 13 which projects laterally fromthe outer surface of the plate and surrounds the shaft to increase thebearing surface thereof.

Means are provided' for taking the thrust of the shaft in both axialdirections. Although capable of various constructions, as here shown asan example, a flange 14 is provided on the shaft and lies against theinner surface of the frame plate, 11. For reducing wear on the metal, aflat washer 15 of leather or other material may be interposed l on theshaft between the flange and plate.

' rIhe shaft is shown with a collar 16 keyed thereto on the inner'sideof the fiange. Be yond this collar, the rotor isv located. The flangemay be formed as an integral part of the collar. i

Means" are provided for maintaining the v flange and washer for contactwith the plate.

In exemplifications which embodythe vinvention to what is now consideredthe best adtions, as here shown as an example, `lamplate provided withside extensions 18, through which extend studs'19 -having heads 2Ofand`Vscrew-threaded ends 21 passing through tapped holes' in fra-me platev11.' Coiled springs 22 surround the studs between the heads thereof andthe plate 17 and lock nuts 23 yare screwed on the lthreaded 'ends ofthe4 studsand against theouter surface'of the frame plate 11. The endsof the studs are slotted as at 24 to vallow convenient turning thereof,as by a screw driver, fronithe exte-l's Vrior of the condenserandeasyaccessibility" thereto.

The plate 17 is urged by the sprin s toward the frame'plate 11v andclamps the ange and washer against the same.

and in the other direction by the compression springs. In addition,there is provided a frictional retarding force tending to prevent Thrustin one direction is thus resisted by the frame plate,"

condition of the flange. The shaft and rotor carried thereby areconsequently maintained in their adjusted positions. The adjustments ofthe studs increase or diminish the amount of friction and the rightamount can be obtained by such adjustments. The frictional resistanceshould be such as to permit turning of the shaft without difficulty andgreat enough to maintain the shaft in the position adjusted to inturning the condenser.r- The use of the double spring constructionherein illustrated provides an even distribu tion of force on the iiangeand a well-balanced construction. In addition, this form of constructionrenders the adjusting devices easily accessible and the whole bearingmayI be assembled andY dismounted lconveniently and quickly.
